Abstract: A transmission chain for a continuously variable conical pulley drive, comprising a plurality of interleaved sets of link-­plates for each link, and an associated transverse-plate for each set. Each link-plate has at least two cams (43) per longitudinal sside, defining between them a groove (44) with preferably V-shaped sides opening towards the cam-tops. Each associated transverse-­plate has a rectangular closed window (54) and longsides (58) shaped correspondingly to the grooves (44). In service, when run­ning through the sheaves of the pulleys, the transverse-plates locate themselves free-of-play in the grooves of the link-plates reducing wear and noise and any tendency for the chain to run out of square. At the straight trajects, play between the transverse-­plates and the link-plates is restored again, permitting luboil to enter.

Abstract: A deployment arrangement comprises an inner tube 10 pivoted to ground at 'P' and carrying an outer tube 12 for telescoping movement. The inner end of the outer tube 12 carries a collar assembly 14 which is pivotally connected to a drive or radius arm 18 which is pivoted to ground at 'Q'. The radius arm 18 carries a drive plate 50 which defines a cam track in which a cam follower runs. The mechanism is driven by a ram 20. On actuation of the ram 20, the consequent rotation of a drive plate relative to the collar assembly 14 initially executes a programmed rotation of the outer tube 12 about its longitudinal axis and then locks the outer tube against rotation. Thereafter, the outer tube 12 extends telescopically relative to the inner tube and the inner tube pivots about 'P'.

Abstract: In a network in which conflicts may arise because of simultaneous requests from several users, the invention provides for granting immediate access to the applicant provided that within a set period of time before the applicant's request is registered, no other request has been emitted. Otherwise, the network controller monitors the activity, and when the activity ceases it verifies that during an arbitrarily set lapse of time no other request for access was received. If this is the case, a verification message is sent to the caller, upon which said caller is granted access to the network only after he has acknowledged the message before a set time.

Abstract: A test tube handling assembly has an elongate member (12) with an end for engaging a test tube (14) and an end opposite thereto driven about an axis of the member for orbital movement with its axis. The member is a slender rod with a spherical bearing about a center part thereon between the ends thereof and along its axis. An arm (23) extends from a support to carry the spherical bearing and permit limited motion of the rod relative to the support. A gripping means (28) on the end for engaging the test tube holds the test tube and its contents during movement of the rod relative to the axis. A drive (34) located on the support near the end opposite causes the test tube to swing about the center part. Contacting means with a seal for closing the open end of the test tube is part of an inflatable bladder (32) which holds the open end of the test tube by fitting in the open end of the test tube. The drive has a motor (35) for providing orbital motion. The motor axis (36) and the member axis (16) are in spaced parallel relation relative to each other with a linkage means therebetween to cause the axis of the member to move about the axis of the motor imparting an orbital motion to the end opposite of the member thereby orbiting the end for engaging the test tube. A three axis positioning means (19) carries the support by connection with a releasable latching means. A method has steps of holding a test tube by the gripping means, moving the test tube repetitively with the drive and generating orbital movement of the test tube and sample therein for producing a vortex in the test tube sample.

IPC: A61B5/0215
Filed: 1990-02-02
Abstract: Several improvements in fiber optic sensing systems are disclosed. One improvement incorporates a dielectric filter applied directly to the sensing end of an optical fiber detector which has the characteristic that it reflects back a reference light beam of one wavelength while passing a sensing signal of a different wavelength which is modulated in some predetermined fashion beyond the filter. Both light signals are reflected back through the fiber and are, accordingly, attenuated in an identical or nearly identical fashion in response to various noise sources . The ratio of the intensity of the two signals is proportional to the sensed parameter and renders the system essentially self-compensating. The dielectric filter is preferably directly coated onto the exit end of the fiber through vapor deposition techniques. Time division multiplexing is used to sequentially fire plural light sources and a single photodetector is used for measuring the intensity of the reflected back signals of the various wavelengths. Another improvement encompasses the detection unit in which the input and reflected signals are separated using an off-axis parabolic mirror which provides excellent separation efficiency. According to another principal feature of this invention, a concave surface is formed at the finer end which increases the numerical aperture of the fiber which provides greater sensitivity to the deflection of a pressure sensitive diaphragm spaced from and confronting the fiber end.
